DETAILED DESCRIPTION OF THE EMBODIMENTS

The present disclosure will be described in detail in combination with the following drawings and embodiments.

Referring to FIG. 1, the combined air passage of an air-supported membrane building includes a composite passage 21, an air pumping device 22, a temperature regulation device 23, and an air inlet passage 24.

The composite passage 21 is provided with a middle inlet 211 and a middle outlet 212. One end of the air inlet passage 24 is in communication with the inlet of the middle inlet 212. The outlet of the air pumping device 22 is in communication with the other end of the air inlet passage 24 and an inlet of the air pumping device 22 is in communication with an outdoor space. The inlet of the temperature regulation device 23 is in communication with the middle outlet 212, an outlet of the temperature regulation device 23 is in communication with an indoor space.

The air pumping device 22 draws fresh air from the outdoor space and pumps it into the air inlet passage 24, through which the fresh air is supplied to the composite passage, and then fresh air enters the temperature regulation device 23 through the composite passage. After the temperature regulation device 23 performs temperature regulation to the fresh air, the fresh air is supplied by the temperature regulation device 23 to the indoor space, thereby implementing the air supply and the temperature regulation in the indoor space.

As the temperature regulation device 23 and the air pumping device 22 are in communication through the composite passage 21, when the air pumping device 22 stops working and the temperature regulation device 23 works normally, a negative pressure is formed in the composite passage 21, the fresh air in the outdoor space can still enter the air inlet passage 24 through the air pumping device 22 and eventually be supplied to the composite passage 21, thereby implementing that the temperature regulation device 23 draws fresh air from the outdoor space through the air pumping device 22, the air inlet passage 24 and the connecting passage. The air pumping device 22 pumps fresh air to the indoor space through the temperature regulation device 23, the air inlet passage 24, and the composite passage 21. As such, it is not necessary to build separate inlets and outlets for the temperature regulation device 23 and the air pumping device 22 respectively, the construction cost is saved.

It should be noted that when the air pumping device 22 stops working and the temperature regulation device 23 works normally, most of the air drew by the temperature regulation device 23 is fresh air from the outdoor space, and only a small portion is the indoor space air that enters the temperature regulation device 23 through the central air pumping opening 213.

The composite passage 21 is provided with a central air pumping opening 213, which is in communication with the indoor space. When the temperature regulation device 23 is not working, the air pumping device 22 can, through the central air pumping opening 213, supply fresh air to the indoor space; when the air pumping device is not working and the fresh air in the outdoor space cannot go through the air pumping device 22, the temperature regulation device 23 can, through the central air pumping opening 213, draw the indoor space air to perform temperature regulation to implement an internal circulation by the temperature regulation device 23 thereby allowing a better independence from each other between the temperature regulation device 23 and the air pumping device 22.

The combined air passage further includes an air returning passage 25. One end of the air returning passage 25 is in communication with the air returning opening of the air pumping device 22, and the other end is in communication with the indoor space to implement that air pumping device 22 can, when drawing air, draw both outdoor fresh air and indoor space air at the same time and mix the air and supply the mixed air to the indoor space to implement the air inside and outside circulation in the indoor space. The returning opening of the air pumping device 22 can further be provided with an air mixing valve (not shown) which is used to regulate the mixing ratio of outdoor fresh air and indoor space air. Certainly; to ensure the purity of the air entering the indoor space, an air purification module(not. shown) can be located inside the air pumping device, the air purification module can be used to purify the air entered into the air pumping device and then supply the air through the air transmission opening of the air pumping device.

In order to protect the port of one end of the air returning passage 25 and the central air pumping opening 213, the combined air passage further includes a first air-guiding window 26 and a second air-guiding window 27. The first air-guiding window 26 is fixed at the port of one end of the air returning passage 25, the second air-guiding window 27 is fixed at the central air pumping opening 213. In the present embodiment, the shapes of both the first air-guiding window 26 and the second air-guiding window 27 are grid-like, so that the outgoing air passing through the central air pumping window 213 and the port of one end of the air returning passage 25 can disperse in different directions to effectively generate an air circulation and advantageously reduce the speed of the outgoing air.

It should be noted that the number of the middle inlet 211 or the port of one end of the air returning passage 25 are not limited to one, it can be plural and located at different locations in the air-supported membrane building. In addition, the temperature regulation device 23 can be located in the indoor space, or the outdoor space. When the temperature regulation device 23 is located in the outdoor space, an air passage for air supply from the temperature regulation device 23 to the indoor space is required to be built.

In the embodiment of the present disclosure, the temperature regulation device is in communication with the air pumping device through the composite passage, such that the outlet of the air pumping device and the inlet of the temperature regulation device share the same opening, and it is not necessary to build separate inlets and outlets for the temperature regulation device and the air pumping device respectively, the construction cost is saved. Besides, since the temperature regulation device is in communication with the air pumping device through the composite passage, when the air pumping device stops working and the temperature regulation device works normally, the negative pressure is formed in the composite passage, thus the fresh air from outdoor can still enter the inlet passage through the air pumping device and then be supplied to the composite passage through the inlet passage and eventually enters the temperature regulation device, which can pump the air into the indoor space and can implement the temperature regulation. The composite passage is further provided with the middle inlet which is in communication with the indoor space. When the temperature regulation device stops working, the air pumping device can supply air to the indoor space through the central air pumping opening. When the air pumping device stop working, the temperature regulation device can still draw fresh air from outdoor to perform temperature regulation, alternatively, the temperature regulation device can draw air from indoor directly through the central air pumping opening for temperature regulation, such that the temperature regulation device and the air pumping device can work independently from each other.
